W'ARP-SZNG MACHNE.

Application filed, July 13,

rihis invention relates to machines used in the textile industry for sizing warp yarn and commonly referred to as fslashersi Y lillachines of this type include a sizing tank equipped with rclls for guiding the yarn through the sizing in theV tank, squeeze rolls which squeeze the surplus sizing out of the yarn, one or more drying cylinders over which the yarn passes immediately after leav'.ig the squeeze rolls, leese rods, and a delivery roll which advances the yarn to a beam on which the yarn is finally wound. A great many strands or ends of yarn are runthrough the slasher at atime. Villen it is necessary to stop the machine to count in or lay in a new set of ends, the sizing hardens on the size and squeeze rolls and on the yarn which has just passed through the sizing bath. Consequently, b efore the machine can be started again it is necessary to wash off this hardened sizing. lt is inevitable that the sizing will be washed off a section of the yarn immediately adjacent to the squeeze rolls and which has already passed through these rolls. Vfhe unsized yarn is much weaker than the sized yarn, andv if the yarn from whichthe sizing has been washed is allowed to go through the machine in this manner, it is likely to cause a great deal of trouble in the subsequentoperation of weaving due to the fact that the unsized sections of yarn are weak and consequently likely to break. lt is necessary, therefore, after counting in a new set ofende to throw away the unsized section of yarn. Furthermore, all the yarn in the machine must be discarded with this Waste section since the length of yarn between the size rolls and the delivery roll could only be saved by piecing up. rlhe labor involved in performing this operation obviously would cost more than the value of the yarn to be saved.

1t is the chief object of the present invention, therefore, to improve machines of this type with a view to eliminating this waste of yarn.

-The nature of the invention will be readily understood from the following descrip'- tion when read in connection with the accompanying drawings, and the novel features will be particularly pointed out in the appended claims.

In the drawings,

Fig. 6 is a side elevation showing the driving mechanism for the cylinders;

Fig. 7 is a vertical cross sectional view through the sizing tank and adjacent parts; and

Fig. 8 is a cross-sectional plan view showing' certain details of the driving mechanism for the cylinders.

Referring firstto Figs. 1 and 2, the strands of yarn are drawn from supply rollsor section beams, indicated at 2, and they pass over a guide roll 3, under a takeup roll 1, and over guide rolls 5 `and 6 to an immersion roll 7 which is mounted to rotate freely in the sizing tank 8. The yarn next passes between a size roll 9 and a squeeze roll 10, thence between another size roll 12 and squeeze roll 13, next over the large drying cylinder 14, and thence over the small cylinder 15, between the leese rods 69 and through the comb 7() to the delivery roll 16. VFrom this roll the yarn passes to the loom beam 17 on which it is wound in readiness to be transferred to the loom.

rThe machine is driven through a variable speed mechanism comprising two cones 18 and 19, Fig. 2, which are connected by a belt 20. A pinion 641 mounted on the shaft of thecone 19 drives the delivery roll 16 by means of the delivery roll gear 65 which, in turn, drives the loom beam gear 66. The shaft of the delivery roll carries a bevel gea-r 21, driving a bevel pinion 22 which is keyed on a side shaft 23 that extends the entire length of the machine. Both the drying cylinders in the present machine are driven from the shaft 23. The driving connections between the shaft 23 and the cylinder 14 are best shown in Figs. G and 8, from which it will be seen that the shaft 23 carries a mitre gear 241, driving a similar gear having a rear 26 secured tast thereto. rlhis ,gear meshes with a pinion 27 tast on a 23 to which is lined a pinion 29 Which meshes with the teeth oii a ring' gear boltec to the end of the cylinder le.

neetions between the shalt 23 and the cylinder l5 drive the latter cylinder.

At its rearward end the shaft 23 drives a pinion 32, 2, through mitre gear connection 3l, and this pinion meshes with gears 33 and 3st, respectively, which are tast on the ends of the sha-tts which carry the size rolls 9 and l2. rllhe eonstructionso tar described is substantially like that which has been used heretofore. i

lt will be observed that the yarn is ted through the machine 1oy the sizing rolls, cylinders and delivery roll, all oi which are positively driven. ilso that the direction oi rotation of all these parts depends upon thedirection et rotationot the cone 18, and that it the direction ot rotation et this cone is reversed, the entire machine will be reversed.

The driving mechanism of the machine is best shown in Figs. 3, il and 5 and comprises a pulley 36 tast on the shaft 37 on vi'hioh the cone 13 is fastened, a slow speed pulley 39 which is keyed on a sleeve l0 that rotates treely on the shaft 37, and a loose pulley 38 mounted to'turn it'reely on they sleeve d0. fr pinion -l-l is secured to this sleeve d@ and meshes With a gear 42 lreyed to a shaft d3. A pinion le is mounted slidahly on hut is splined to the shaft ii-3, and when in the position shown in F 3, d and 5, the pinion le meshes with and drives a Agear l5 which rotates loosely on the shaft 37, finother pinion 4l@ `which is integral with the gear d8 and turns freely on a `shaft d'7 n'iounted above the shaft 43, also meshes "with the gear l5 but normally rotates idly. rlhe pinion 411i, however, is arranged to he moved out ot mesh with the gear l5 and into mesh. with the gear d8. At this time, therefore, the gear will be driven in a reverse direction through the normally idle gears t6 and d8.

is above stated, the gear t5 is loose on the `shalt 37, ont it is arranged to 'drive this shalt in either direct-ion through ratchet wheels and 51, respectively, 3 and el, mounted at opposite sides et the gear. rlhat is, the gear oar ies tivo paivls and 53 which are arranged to engage, respectively, with the ratchet Wheels 50 and 5l. ri spring 541; which partially encircles the hub of the stationary arm 5S has one end positioned between tvvo pins 55 and 56, respectively, that project from an arm integral With the paivl 52. Another spring 57 partially encircles the huh ot the ratchet Wheel 5l and is similarly connected with the paivl 53. By referring;` to Fig. a it will be seen that When the gear l5 is driven in a counter-cloclnvise Similar con-" nenas-ie direction, carrying the pavvl with it, the

pin 5G will drag the spring 5a along With the paivl and this dragging action will tip the pavvl in counter-clockwise direct-ion a id bring it into engagement with the teeth oft the ratchet Wheel 50. This Wheel is sew 55. At the same time, the spring 57 would tip the pa'ivl into engagement with the ratchet Wheel and thus drive the shaft in a clockwise direction.

llor the purpose orf shitting the pinion into mesh with either of the gears l5 or d8, the huh oi the pinion del is provided With a groove 419, Fig. 5, to receive a forli or shifter 60 which is carried by a rod (il mounted tov slide horizontally in the machine frame. A strong spring` vacts on 'this rod in a direction to hold the pinion all normally in mesh with the gear inthe moven'ientoiC `the rod -under the influence ot the spring` 62 being limited hy a collar G3, 3. Handles 67,

(i3 are provided at the opposite ends oi the rod Gl so that it may be shifted conveniently hy the Workman.

sstuning that the parts are in the position shown in 3 'and 5, it will be seen that. the machine will he driven `toiavznjrl at high speed when tile driving belt is on the itz 't pulley 35, and that the machine will be en in the same direct-ion at a, much sloweri er speed when the belt is on the intermediate pulley 39. lf the belt is shifted to the loose pulley 33 the machine, ol' course, vwill be stopped lt, however, the holt is on the i11- termediate pulley 39, thus driving the machine 'forward at a` slow speed, and the rod (il should he moved to shit-t the pinion 4A- into mesh with the gear d3, the motion ot all the d ven parts ot the machine would be rever-:ed due to the reversal otl rotation Vof the shatt 3T. rlhe machine speed, however, .vould be even slower than that oilv the torward slow speed due to the ratio Vbetween ti. gears e3 and t6.

ln order to eliminate the danger oit pushing the reverse gearing' `into mesh when the heit is on the high speed pulley, or oi shipping;` the belt from the slow to the high speed pulley when the reverse gearing is in mesh, the-forl or gear shifter GO has a lug- 7l on its shank Which cooperates`^` With a safety arm Z2 mounted on the vertical shipper lever shatt 73, as shown in Figs. 3 and d. rn arm 74, Fig. 2, is secured tast on the shaft T3 and is connected directly to the belt shipper fork and operates it. Another arm 76 also fast on the shaft 73 is connected by means of a link 77 to a hand lever 78. A rock shaft 79 connects this lever with a similar lever 8O at the opposite side of the machine. rlhe shipping of the belt therefore is effected by the movenient of either on-e of the hand levers 7S or S0. The safety arm L has three positions, as indicated in Fig. lt is in position a when the belt is on the high speed pulley in position when the belt is on the slow speed pulley 39, and in position c when the belt is on the idle or loose pulley 38. A

lt will thus be evident that when the belt shipping nechanism is moved to shift the driving belt from the loose pulley 3S to the slow speed pulley 39 or to the high speed pulley 3G, the safety arm 72 will be swung in a clockwise direction, Fig. 8, from the position c to Y) and thence to a. TWhen the arm is in position o with the belton the high Aspeed pulley, it effectually locks the fork (Si) in its forward position, since any attempt to move the fork into position to reverse the gears-will be prevented by the lug '7l strik in g the end of the arm 72.

lt is also evident that when the reverse gearing isin mesh, the lug 7l will be in its dotted line position, Fig. 3, and that it will prevent the safety a m l2 from being moved into position a which is necessary in order to ship the belt on to the high speed pulley.

lVhen the direction of feeding movement or travel of the yarn is reversed, as above described, a certain amount of slack will accumulate between the supply beams 2 and the sizing rolls 9 in the tank 8. rlhis slack, however, is taken up by the heavy takeup roll et. l and 7, located behind the tank 8 (with reference to the normal direc tion of feed of the yarn) and resting on the yarn between the guide rolls 3 and 5, the weight of this roll being sufficient to draw the yarn backwardly over the guide rolls 5 and 6. IThe yarn thus is maintained taut at all times. f y

After the machine has been stopped for the purpose of counting in a -new set of ends, the sizing is washed oil' the size and squeeze rolls before the machine is again started up, exactly as has been the practice heretofore. Incidentally, the sizing will be washed olf the yarn immediately in front of the forward squeeze roll 13. Before the machine is again st rted up, however, the immersion roll and yarn ar-e first raised up out of the sizing tank and the machine then is reversed so that the yarn is fed backwardly across the top of the tank but out of Contact with the sizing. rlhis backward feedin movement is continued until the section of yarn from which the sizing has been washed has been fed back of the immersion roll. The attendant then stops the machine, replaces the immersion roll, so that it forces the yarn down into the sizing bath, and

immediately starts the machine forward slowly, this last operation being performed simply by releasing the rod 6l and allowing the spring GQ to shift the pinion 44 into its normal position, where it directly drives the gear 45. rlhis results in re-sizing the washed yarn. lhen the machine has attained the proper speed, the attendant shifts the belt on to the fast pulley 36.

lt will now be appreciated that this in* x vention avoids the necessity for vasting a substantial quantity of yarn which otherwise would have to be thrown away due to the presence of an unsized section of yarn, as above described. Furthermore, this advantage is obtained through the use of a relatively simple change in the machine. The cost of manufacture of the machine, therefore, is increased by only a trifling degrec, while the annual saving in yarn realized from each machine is very substantial.
